<p>Do you mean json in general or artifact notifications specifically? Neither at present, but I'd like it to cache diagnostics, preferably in json for maximal usefulness. No immediate plans for artifact notifications.</p>

<p>JSON in general.  I'm asking in regards to how future-incompatible warnings work.  I'm curious if you have an opinion on how that should behave.  The idea is to make people aware when a dependency will fail to compile in the future. Cargo collects those warnings from rustc and displays a small summary that can be expanded.  Does Buck also use <code>--cap-lints=allow</code> for dependencies?  If other build systems use cap-lints, I'm wondering if it makes sense to unconditionally show those warnings, or if it should be opt-in.</p>
